Ground Loop Humm/Buzz from Television

Hello:

Any suggestions on the following: I have noticed a humm/buzz in my speakers that I suspect is some kind of ground loop. However, it appears ONLY when the television itself is on and disappears when I turn it off. I tried lifting the ground on the tv (which, by the way, is tied to a properly ground satellite cable/box) but to no avail. I haven't found any precedent in any of the archives so any thoughts out there?

Thanks.
John

You might try grounding the case of the satellite receiver to the electrical ground of the house. I used a wire with spades on both ends, and connected from the satellite receiver to the ground on the electical wall plate. I do not know if this will solve your problem, but it is an easy solution to try.

Just a guess, but, maybe your properly grounded satellite is one ground too many. Forgive me if you already know this, but, you should have an odd number of ground connections. Perhaps a cheater plug on your satellite/cable box might be the trick. Good luck.

Thank you everyone for your responses but I actually think I may have a more serious problem. In doing a little experimenting today, I noticed that every time I plugged the power cable from the tv into an outlet, a little spark jumped from the connection. Bad news, me thinks.
